Disclaimer: Max Pain is a theoretical concept based on the assumption that option writers manage price toward minimum loss. In reality, markets are driven by multiple factors. Max Pain should be used as one data point among many — not as a sole trading signal. Past max pain accuracy does not guarantee future results. F&O trading involves substantial risk of loss. This is not financial advice.

Frequently Asked Questions

What is Max Pain in options trading?
Max Pain is the strike price where option writers (sellers) collectively lose the least money at expiry. It's calculated by summing the intrinsic value of all in-the-money calls and puts at each possible expiry price. The strike with the lowest total pain is the max pain point.
How do I get OI data for Bank Nifty?
Go to NSE website → Market Data → Derivatives → Option Chain. Select Bank Nifty and the relevant expiry. Copy the OI column for both calls (CE) and puts (PE). You can also use Sensibull, Opstra, or your broker's option chain page.
How accurate is Max Pain for Bank Nifty?
Max Pain shows approximately 60-70% accuracy for Bank Nifty weekly expiries — meaning BN closes within 200-300 points of max pain about 2 out of 3 times. It works best in range-bound markets and loses accuracy during strong trends or events like RBI policy days.
When should I check Max Pain?
Most useful on Wednesday-Thursday for Bank Nifty weekly expiry. Check on Monday for initial reference, then update OI data on Wednesday for the most relevant reading. Max pain can shift during the week as OI changes.
What does it mean if spot is far from max pain?
If Bank Nifty is trading significantly above or below max pain (500+ points), it suggests strong directional momentum that overrides the gravitational pull of max pain. In such cases, max pain may shift toward the current price over the next few sessions as new OI builds.
